I consider video games to be an art form... that said, I cannot believe the studio green-lighted this mission, or sequence, or whatever you want to call it. I am almost compelled to cancel my pre-order, after having watched the footage.
Yes, you can kill innocent bystanders in other video games. But never, that I can recall, has a studio ever put the player in the role of a terrorist tasked with killing a mass of unarmed civilians. The COD franchise took a bold step when they left a settled, old war and took to mirroring the real-world fight on terrorism - but this is absolutely beyond "edgy" - it is in absolute bad taste.
I bet somebody gets fired over this.
